Its not easy printer.
But if you know, what are you doing, then ...for the money, they deliver excellent result.
But remember, nobody will teach you, how to use it,
Nobody will supply SW, and upgrades.
You have to figure out everything alone.
You need to learn, read similar topics, learn and read similar printers (Formlabs has excellent forum)
No automatisation, no "clever " software.
You will definitely spend some time with it, and around it
If you are happy with this, then the printer is near to perfect.
I will buy it again.
The printer allows me to learn a lot (pish me to learn a lot). With concrete questions you can ask, people will answer you.
Its much easier to buy a ready made printer and eventually modify it, then build a new one (I built a DLP printer and bought this PRONIKS)
